  • Converting series of images with ffmpeg results in black video [migrated]

    27 avril 2013, par Marco Gagliardi

    I've just downloaded ffmpeg since it seems to perfectly match my needs (make a video from a set of pictures). I'm currently playing around with some examples just to get started and there's something weird happening that I can't explain.
    I'm trying this command (provided in the official documentation) :

    ffmpeg -f image2 -pattern_type glob -i 'foo-*.jpeg' -r 12 -s WxH foo.avi

    on a data set of 10 jpg pictures (of course I changed the pattern with '*.jpg'). The video seems to be encoded correctly but it's simply too fast to be sure about that (anyway it stops on the last frame that corresponds to the last picture). In order to get a longer video i thought to low the frame rate from 12 to 1 (one sec each picture) or 0.5 (2 sec each one) and so on.. no way ! with low rate values even if the video is played the pictures are simply not displayed. The player (VLC in my case) just shows a blank/empty video for a few seconds.

    Am I making something wrong or have I misunderstood the -r parameter ? Is it something related to codecs involved ? Finally.. How can i get each picture displayed for 1 or 2 seconds ?

    Here's the output :

    MacBook-Pro$ ffmpeg -f image2 -pattern_type glob -i '*.jpg' -r 1 -s 200x300 foo.avi

  • Converting Real Media with ffmpeg

    22 avril 2018, par Eric Arenson

    I have a number of old crusty Real Media files I need to convert and was hoping to write a script to batch process them. I’m able to do a Real Media -> AVI conversion with FFMpegX, but when I try to replicate the conversion with ffmpeg, it always errors out with something like :

    [avi @ 0x10084fa00] Too large number of skipped frames 117425 > 60000

    It may have something to do with the funky format of these Real Media files :

    Does anyone have any tips on either how to find out what FFMpegX is doing to make the conversion work, or a better way to go about using ffmpeg to do this ?

    EDIT

    Including the ffmpeg command (thank you to @Mondain for teaching me about the stream mapping !) and output :

  • Media contaner which supports uncompressed audio and video

    21 juin 2017, par Denis Kokorin

    I want to produce uncompressed video and audio programmatically and feed it via stdin to ffmpeg.
    I need uncompressed, because I don’t want to encode video and audio in my code.

    I found here the way to create video only file from uncompressed rgb24 input stream. But I do need to create both video and audio.

    Which container supported by ffmpeg can contain uncompressed video and audio ?
